East China’s Jiangsu province has stepped up the construction of major investment projects and ensured their smooth progress against the sweltering heatwave so as to fulfill goals for social and economic development set forth in this year’s government work report. Our staff reporter has the story.
At the construction site in Jintan District, Changzhou, the last ballastless track slab of the South Yangtze River Intercity Railway was poured in the early hours of Monday morning.
48.67 kilometers of ballastless track has been laid in this section, one month ahead of schedule, laying the foundation for the subsequent track laying construction.

We operate 24-hour shifts on site, carefully adjusting and pouring the track slab, ensuring that the track is accurate to 1.5mm through a one-shot molding process.
The South Yangtze River Intercity Railway is designed with a speed of 350 kilometers per hour and paved with a new type of slab ballastless track independently developed by China.
The construction of the concrete filling layer and the adjustment of the track slab are carried out at night to reduce the impact of temperature fluctuations on the accuracy and ensure that the construction accuracy meets the design and specification requirements.
With the "Pengcheng No. 1" shield machine cutter head coming out of the hole, the first shield section of Xuzhou Metro Line 6 was successfully completed on Monday.
Connecting Tongshan District, Xuzhou New City and the East High-speed Railway Station, the subway line has a total length of 22.9 kilometers with 16 stations installed. The fully automatic driverless technology will be adopted for the first time, which is of great significance to improve the rail transit framework network in Xuzhou and expand the urban space.

During the construction process, the project team has overcome the risk sources such as shield tunnels passing through residential buildings,commercial buildings, rivers, bridges, etc. At the same time, we have comprehensively used AI and smart factories, to ensure the safe and smooth arrival of our shields.
